Abstract

The magnetic material of the system Sm-Fe-N has a crystalline, magnetically hard phase having the Th2Zn17 crystal structure in whose crystal lattice N atoms are incorporated. According to the invention, this magnetic material is to be prepared by first producing, as an intermediate of the material to be prepared, a sintered element (2) with the two-component Sm-Fe phase from Sm-Fe powder aligned in a magnetic field. The intermediate is then heated in a nitrogen atmosphere, the magnetically hard phase being formed. The nitrogen atmosphere advantageously contains reactive nitrogen (N<*>). <IMAGE>
